Optimal lognormal distributions of core radius and shell thickness in an ensemble
of hollow gold nanoshells exhibiting maximum average [(a) and (b)] absorption and
[(c) and (d)] scattering efficiencies forσ=σR=σH=0.1, 0.25, 0.5, and 1.0. The simulation parameters are the same as in Figures 1(a) and 1(b).
